Description
Die Neuerung bezieht sich auf eine Anordnung als Baukastensystem zur Steuerung von Differentialzylindern, insbesondere für Mobilkräne, wobei ein Grundelement mit hydraulischen Verbindungskanälen und integrierten Ventilelementen, wie Druckwaage, Druckbegrenzungsventile, aufweist und nach außen geführte Anschlüsse für Verbindungen zur Pumpe und zum Tank sowie elektrische Anschlüsse besitzt sowie eine Aufnahmefläche mit Verbindungsbohrungen für mehrere aufflanschbare Module zur Steuerung einzelner ansteuerbarer Differentialzylinder aufweist, die korrespondierende Anschlüsse zu den Verbindungsbohrungen besitzt und das Modul ein Wegeventil für eine Richtungssteuerung aufweist, um über eine Pumpe Öl jeweils auf einer Zylinderseite zuzuführen sowie abfließendes Öl einer Zylinderrückseite zu einem Tank führbar ist.The Innovation refers to an arrangement as a modular system for Control of differential cylinders, in particular for mobile cranes, wherein a Basic element with hydraulic connection channels and integrated valve elements, as pressure compensator, pressure relief valves, and has outwardly directed connections for connections to the pump and the tank and electrical connections and has a receiving surface with Connecting bores for several flanged modules for controlling individual controllable Differential cylinder has, the corresponding terminals to the Has connecting bores and the module has a directional control valve has to over a pump oil each to be supplied on one side of the cylinder as well as draining oil one Cylinder back feasible to a tank is.
Anordnungen dieser Art sind in der Hydraulik bekannt, um mehrere Differentialzylinder eines gebildeten Systems anzusteuern und eine Vereinfachung unter Fortfall von Mehrfachverbindungen zu schaffen sowie Montage und Austausch einzelner Module wirtschaftlich durchzuführen.arrangements This type are known in hydraulics to multiple differential cylinders an educated system and a simplification under Elimination of multiple connections as well as assembly and Exchange of individual modules economically.
Ferner ist es grundsätzlich bekannt, für Differentialzylinder auch eine Eilgangschaltung über ein Wegeventil vorzusehen, wobei ein aus der Zylinderringseite abfließendes Öl nicht zum Tank, sondern zusätzlich zur Zylinderbodenseite geführt wird.Further it is basically known for Differential cylinder also provide a rapid traverse over a directional control valve, a flowing out of the cylinder ring side oil not to the tank, but in addition to Cylinder bottom side out becomes.
Die Aufgabe der Neuerung ist es, unter Berücksichtigung der vorliegenden Verhältnisse standardmäßig eine Grundplatte für alle Einsatzfälle vorzusehen und zu bestücken, um bedarfsweise eine Eilgangschaltung und eine normale Ansteuerung von zugeordneten Differentialzylindern zu gewährleisten.The Task of the innovation is, taking into account the present conditions one by default Base plate for all applications provide and equip, if necessary, a rapid traverse and a normal control to ensure assigned differential cylinders.
Die Lösung dieser Aufgabe besteht neuerungsgemäß darin, daß weitere abweichende wahlweise Module ausgebildet und wahlweise auf der Aufnahmefläche des Grundelementes aufflanschbar einsetzbar sind, die neben einem Wegeventil zur Richtungssteuerung ein zusätzliches Wegeventil als umschaltbares Eilgangsventil aufweisen und das abfließende Öl der Zylinderrückseite zusätzlich der anderen Zylinderseite zuführbar ist.The solution This object is renewal in that further deviating optional Modules formed and optionally on the receiving surface of the Basic element can be used flanged, in addition to a directional control valve for directional control an additional Have directional control valve as a reversible rapid-change valve and the effluent oil of the cylinder back additionally the other cylinder side fed is.
Hierdurch ist es möglich, unterschiedlichen Anordnungen Rechnung zu tragen und unter Beibehaltung der Vorteile einer Grundplatte gegebenenfalls einen Austausch vorhandener Module vorzunehmen, um einmal eine Ausfahrgeschwindigkeit nur mit normaler Geschwindigkeit oder umschaltbar zwischen Normal- und Eilgang vorzunehmen.hereby Is it possible, take into account different arrangements and while maintaining the benefits of a base plate optionally an existing replacement Modules to make an exit speed only with normal speed or switchable between normal and rapid traverse make.
Es ist dabei vorgesehen, daß das zusätzliche Wegeventil des Moduls als Eilgangsventil als 3/2-Wegeventil ausgebildet ist.It is provided that the additional directional valve of the module is designed as a rapid-action valve as a 3/2-way valve.
Ferner wird vorgeschlagen, daß jedes Modul an seiner Oberseite hydraulische Anschlüsse für einen Differentialzylinder und elektrische Anschlüsse zur Ventilsteuerung aufweist.Further It is suggested that each Module on its top hydraulic connections for a differential cylinder and electrical connections to Valve control has.
Zusätzlich ist vorgesehen, daß die wahlweise aufgebrachten Module parallel nebeneinander auf dem Grundelement angeordnet sind.In addition is provided that the optionally applied modules parallel next to each other on the base element are arranged.
In der Zeichnung ist ein Ausführungsbeispiel der Neuerung schematisch dargestellt. Es zeigen:In the drawing is an embodiment of Innovation shown schematically. Show it:
